original application -iiiea :une 4, 192s,

Y This is a'division of my application Serial `No. 282,750 filed June 4, 1928, for improve-- ments in power churns.- n Che invention relates to Va novel connection between the driving mechanism and the Y said drum, and to prevent egress of said contents into said connection thus eliminating collection of said contents .in said connection and a resulting unsanitary condition.

Another object isto provide a connection which will not be distorted by'swelling or other detrimental movements of the drum.

n the accompanying' drawings, a selected embodiment of the invention is illustrated and, therein, y

Fig. 1 is a view partly invelevation and partly in section depicting my improved conneet-ion;

Fig. 2 is a lsectional view takensubstantially on the line 2-'2 on Fig. 1; and Y,

Fig. 3 is a sectional view'taken substantially on the line 3--3 on Fig. 1.

Referring to the drawings, 1 indicates a 1 casing in which a suitable driving mecha-1v nism for the churn is mounted, which diiving mechanism includes a regulatingv handle 2 movable into different positions to regulate the operation of the churn.' The driving mechanismV also includes a ring gear 3 mounted onthe hollow Yshaft 4 journaled in bearings 5., 5 supported in the casing 1. A flange 6 on the hollow shaft 4, extraneous the casing 1, has circumferentially spaced openings 7 therein through which bolts 8 are extended. To the end wall 9 of the drum of the churn a spider 10 is secured which includes an annulus 11 through which bolts orv the like .12 are lextended to connect the annulus to the wall 9. r`The arms 13 of the spider support a circular portion 14 having openings ltherein in which busli Y ings 16 are mounted. The'bushings ,16 have openings 17 therein of greater diameter than .side of said churn and extending through vsaid packing gland, said roll box having a Serial No. 282,150.- Divided andths application led February 2e, ieee.L seria; 'no'. 431,387.4 l Y the diameter of the boite e, Said bolts. being engaged bythe nuts.18.: By reason of the diderence in diameter of the openings 17 and the bolts 8 a semi-exible connection is .providedjbetween't'he spider and the kflange 011555 the shaft'4 an'dlthus anydistortion ofthe drum due swellingy willhave no affect upon the driving'mechanism.y A roll 19 inthe kvdrumis rigidly mounted in the roll box 20 mounted adjacent to the wall 9. The roll box 60 20 includes a sleeve 21 extended through the pack-ing gland 22 including the packing gland collar 23 mounted in the opening 24V inthe wall 9 andthe packing gland sleeve 25.Y rl`he packing gland sleeve 25 hasa flange 26 there' B5 onand bolts 2'? are extended through openkingsinthis iiangeand are screw-threaded yinto openings in the end ofthe packing gland Y :collar '23. .The packing gland collai` 23 inchicles a'vfiange VV28 connected `toA the walll 94770 by' thefbolts 29and the nuts 30. The roll shaft S31-iis journaled in bushings 32 in the hollow shaft 4 and has asquare end 33 fitted into ia similarlyshapedsccket 34 in the sleeve 21; A gear isinounted on the shaft 31H75 A andisfoptionally connected tothe drive mechanisms yin the casing 1. y.'l`heinanner in `which the gear 35' is operated is clearly setV forth inthe heretofore referredv to application.

s It is manifest Afrom the-foregoing descrip-' 53 tion that l haveprovided a connection betweenthe driving mechanisms andthe drum and roll-,ofi power churn which will very effectively accomplish the objects of the invention. y

While l :have set forth a preferredV form of construction for my invention, this is capable' of r.variation andly modification without depart-ingl from the purview of the follow ing claims: i i

I claim:

' p 1.111 a churn, a roll in said churn, a. packing gland secured to the end of the churn and outside thereof, a roll box arranged insquare opening therein, and a shaft having a squareend adapted to engage said opening for forming a driving connection between the roll and shaft. 1m

2. In a churn, a gear shaft, a flange on said gear shaft, a spider, and means extending through clearance holes in said spider for connectino' said spider to said flange in a semi-flexible manner.

3. In a churn, a gear shaft, a flange on said gear shaft, a spider, and means extended through clearance holes in said spider and close litting holes in said flange for connecting said sp1der to said flange in a semi-flexible manner.

4. In a churn, a. gear shaft, a flange on said gear shaft, a spider having clearance openings therein, bolts extended through said clearance openings and openings in said flange for connecting said spider to said flange, and means for connecting said spider to said drum.

5. In a churn, a roll in said churn, a pack- 2 ing gland at one end of said churn extending outside thereof, a roll box inside said churn having a portion extended through said packing gland, said portion having a socket therein in which the polygonal end of a shaft of a driving mechanism may be fitted.

6. In a churn, a drum, a driving mecha` nism including a hollow shaft, a roll operating shaft in said hollow shaft, a packing gland on one of the heads of said drum, a roll box extended through said packing gland, means connecting the roll of the churn toy said roll box, means connecting the roll operating shaft to the roll box, and means connecting the hollow shaft to the head of the drum whereby said drum may be rotated by rotation of said hollow shaft and said roll may be rotated by rotation of said roll shaft.

7. In a churn, a driving mechanism includf ing a roll operating shaft journaled therein, said churn including a drum embodying a head having an opening therein, means tightly mounted in said opening providing a packing gland, a roll box in said drum having a portion extending through said packing gland and having one end of the roll of the churn tightly connected thereto to prevent leakage thereby, means connecting said hollow shaft to the head of the drum, and means connecting the roll operating shaft to said roll ybox extraneously of the connection of said roll to said roll box.
